Convert 287 from decimal to binary

(base 2) notation:

Raise our base of 2 to a power

Start at 0 and increasing by 1 until it is >= 287

2^{0} = 1

2^{1} = 2

2^{2} = 4

2^{3} = 8

2^{4} = 16

2^{5} = 32

2^{6} = 64

2^{7} = 128

2^{8} = 256

2^{9} = 512 <--- Stop: This is greater than 287

Since 512 is greater than 287, we use 1 power less as our starting point which equals 8

Work backwards from a power of 8

We start with a total sum of 0:

The highest coefficient less than 1 we can multiply this by to stay under 287 is 1

Multiplying this coefficient by our original value, we get: 1 * 256 = 256

Add our new value to our running total, we get:

0 + 256 = 256

This is <= 287, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 256

Our binary notation is now equal to 1

The highest coefficient less than 1 we can multiply this by to stay under 287 is 1

Multiplying this coefficient by our original value, we get: 1 * 128 = 128

Add our new value to our running total, we get:

256 + 128 = 384

This is > 287, so we assign a 0 for this digit.

Our total sum remains the same at 256

Our binary notation is now equal to 10

The highest coefficient less than 1 we can multiply this by to stay under 287 is 1

Multiplying this coefficient by our original value, we get: 1 * 64 = 64

Add our new value to our running total, we get:

256 + 64 = 320

This is > 287, so we assign a 0 for this digit.

Our total sum remains the same at 256

Our binary notation is now equal to 100

The highest coefficient less than 1 we can multiply this by to stay under 287 is 1

Multiplying this coefficient by our original value, we get: 1 * 32 = 32

Add our new value to our running total, we get:

256 + 32 = 288

This is > 287, so we assign a 0 for this digit.

Our total sum remains the same at 256

Our binary notation is now equal to 1000

The highest coefficient less than 1 we can multiply this by to stay under 287 is 1

Multiplying this coefficient by our original value, we get: 1 * 16 = 16

Add our new value to our running total, we get:

256 + 16 = 272

This is <= 287, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 272

Our binary notation is now equal to 10001

The highest coefficient less than 1 we can multiply this by to stay under 287 is 1

Multiplying this coefficient by our original value, we get: 1 * 8 = 8

Add our new value to our running total, we get:

272 + 8 = 280

This is <= 287, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 280

Our binary notation is now equal to 100011

The highest coefficient less than 1 we can multiply this by to stay under 287 is 1

Multiplying this coefficient by our original value, we get: 1 * 4 = 4

Add our new value to our running total, we get:

280 + 4 = 284

This is <= 287, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 284

Our binary notation is now equal to 1000111

The highest coefficient less than 1 we can multiply this by to stay under 287 is 1

Multiplying this coefficient by our original value, we get: 1 * 2 = 2

Add our new value to our running total, we get:

284 + 2 = 286

This is <= 287, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 286

Our binary notation is now equal to 10001111

The highest coefficient less than 1 we can multiply this by to stay under 287 is 1

Multiplying this coefficient by our original value, we get: 1 * 1 = 1

Add our new value to our running total, we get:

286 + 1 = 287

This = 287, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 287

Our binary notation is now equal to 100011111

We are done. 287 converted from decimal to binary notation equals **100011111**_{2}.

We are done. 287 converted from decimal to binary notation equals **100011111**_{2}.
